Protocol Handler
|
||
|
|
</h1>
|
||
|
|
<h3>The <code>app</code> module provides methods for handling protocols.</h3>
|
||
|
|
<p>These methods allow you to set and unset the protocols your app should be the default app for. Similar to when a browser asks to be your default for viewing web pages.</p>
|
||
|
|
|
||
|
|
<p>Open the <a href="http://electron.atom.io/docs/api/app">full app API documentation<span class="u-visible-to-screen-reader">(opens in new window)</span></a> in your browser.</p>

<div >
|
||
|
|
<button id="open-in-browser" class="js-container-target demo-toggle-button">Launch current page in browser
|
||
|
|
<div class="demo-meta u-avoid-clicks">Supports: Win, macOS <span class="demo-meta-divider">|</span> Process: Main</div>

<a href="electron-api-demos://open">Now... launch the app from a web link</a>
|

</section>

|
||
|
|
<p>You can set your app as the default app to open for a specific protocol. For instance, in this demo we set this app as the default for <code>electron-api-demos://</code>. The demo button above will launch a page in your default browser with a link. Click that link and it will re-launch this app.</p>
|
||
|
|
<h5>Packaging</h5>
|
||
|
|
<p>This feature will only work on macOS when your app is packaged. It will not work when you're launching it in development from the command-line. When you package your app you'll need to make sure the macOS <code>plist</code> for the app is updated to include the new protocol handler. If you're using <code>electron-packager</code> then you can add the flag <code>--extend-info</code> with a path to the <code>plist</code> you've created. The one for this app is below.</p>
